LOCK.

SPECIICATION forming part of Letters Patent No. 756,276, dated April 5, 1904.

Application filed August 22, 1903.

To @ZZ wwnt it may concern:

Be it known that I, GsPR vON POHY, judge, of Torna, inthe Empire` of Austria- Hungary, have invented certain new Improvements in and Relating to Locks, of which the following is a specification.

This invention relates to a lock the latch of which can be opened or closed from a distance mechanically without the aid of springs.`

In the accompanying drawings the improved lock is shown in Figure 1 in a front View, the lock-plate being partly broken away. Fig. 2 is a section on line I I of Fig. 1. Figs. 3 and 4 are sections on line II II of Fig. 1, the device for securing' the latch being shown in locked or opened position. Fig. is a detail view showing a common form ci' connection for the bucket-lifting arm. Fig. 6 is a fragmentary detail taken on the line 6 6 of Fig. 5. y

The latch 2, which is inclosed, as usual, in the lock-case 1, rests on suitable supports and is guided on a roller 3, which projects through a longitudinal slot 4 of the latch. An anglelever 6, pivoted at 5 to the lock-case, serves for moving the latch to and fro. The anglelever 6 is connected with the latch by means of a stud 7, which projects horizontally from the lower end of the angle-lever and engages with a vertical slot 8 of said latch. The free end 9 or' the other arm 6 of the angle-lever is weighted and provided with a horizontal stud, to which a cord 10 is attached. The cord 10 is conducted over a suitable number of guiderollers 11 to the place from which the opening or closing of the door is to be eiiected. In locked position the front end of the latch 2 engages with a staple-plate 12 in the well-known manner and is secured in this position by the weighted end of the angle-lever 6. I/Vhen the cord 10 is pulled in the direction of the arrow a, Fig. 1, the latch is moved backward by the bolt 7 of the angle-lever 6. When the cord was released, the angle-lever would immediately effect the forward movement of the latch. To prevent this, a catching device is arranged, which is shown in Figs. 2, 3, and 4. On the back wall 13 of the lock-case a casing 14 is Xed. In this casing 14 a spoon-shaped bucket 16 is pivoted at 15, which contains a loose ball Serial No. 170,449. \N0 model.)

17. In the front wall of the casing 14 an opening 18 is provided. The arm 6 of the anglelever is inclosed between the front wall of the casing 14 and the front wall 19 of the lockcase. When the door is closed, the arm 6 of the angle-lever is in the position shown in Fig. 3. From the inner surface of arm 6l of the angle-l ever projects a stud 20, to which an arm 21 is linked, which forms a knee-joint therewith. The bucket 16 is provided with a lateral projection or shoulder 22, with which the arm 21 is adapted to engage. As shown in Figs. 5 and 6, the arm 21 is pivoted to the bent lever 6 by means of a pivot c, around which it is free to turn for a limited movement. The arm is provided with a cheek which in the normal position of the arm rests against a corresponding cheek a, formed on the shoulder 20 of the lever 6, and prevents the arm from turning in one direction. When the lever 6 is lifted by means of the cord 10, the arm 21 being prevented from turning downward will lift the bucket 16 until the arm 6 is above the ball and the lock is opened. By further pulling the cord the arm 21 will slide along the lateral projection 22 of the bucket 16, and the bucket, together with the ball, will fall back into its normal position. l/Vhen the cord is released, the angle-lever will fall down by its Own weight and close the latch. When falling, the arm 21 strikes the lateral projection 22 of the bucket 16 and will turn upward until its end can slide past this projection and it can fall back into its normal position. A spring 28 is further provided in the lock-case, which has a nipple 24 on its lower surface, which, abutting against the upper edge of the casing 14, determines the position of the blade-spring 28.

When the angle-lever 6is acted upon by the pulling of the cord 10, the arm 6 of the anglelever moves upward and by engaging the projection 22 lifts the bucket 16, so that the ball 17 falls through the opening 18 against the inner surface ofthe front wall 19 of the lockcase. If now the cord is released, the arm 6 or' the angle-lever is prevented from falling by ball 17, which is kept in its locking position in consequence of the bucket 16 being retained by the projection 22 engaging with the knee-joint lever 21. If, however, the cord is pulled before it is released, the arm 21 will be drawn away from bucket 16, so that the bucket, and with it the ball 17, return to their original position, so that if the cord l0 is now let free the angle-lever falls and pushes the latch 2 forward into the staple-plate 12.

Having now particularly described and ascertained the nature of this said invention and in what manner the same is to be performed, I declare that what I claim is- Improved lock to be opened and closed from a distance comprising in combination with the usual lock-case and staple-plate, alatch guided by a roller projecting through a horizontal slot of the latch, an angle-lever pivoted in the lock-case, a horizontal stud projecting from the end of the vertical arm of the lever and engaging with a vertical slot of the latch, a weight at the end of the other arm of the angle-lever, a cord attached to the same end of said lever guided over rollers to the place from' which the door is to be opened, a kneejoint arm projecting from the inner surface of the weighted arm of theangle-lever, acasing in the lock-case above the latch, a spoonshaped bucket pivoted in said casing, a loose ball in said bucket, an opening in the front wall of said casing, an arm of the knee-joint projecting from the angle-lever reaching behind the bucket and ablade-spring above said casing to press the angle-lever whenit is lifted, substantially as described and shown and for the purpose set forth.

In Witness whereof I have hereunto set my hand in presence of two witnesses.
